Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616466, here are decompositions:

43 + 31616423 = 31616466
47 + 31616419 = 31616466
73 + 31616393 = 31616466
97 + 31616369 = 31616466
103 + 31616363 = 31616466
107 + 31616359 = 31616466
127 + 31616339 = 31616466
139 + 31616327 = 31616466

Showing the first eight; more decompositions exist.
